The reverse charging protocol module is configured to determine a reverse charging protocol matched with the charging current of the second electronic device. The control module is coupled with the charging module and the reverse charging protocol module, and configured to acquire the reverse charging protocol determined by the reverse charging protocol module in response to the connection between the charging interface and the second electronic device, and control the charging module to adjust the current output to the second electronic device based on the reverse charging protocol. The charging circuit can increase the reverse charging current. |
